About me / 05

I'm Subhamoy, a Computer Science student focused on backend engineering, GenAI and agentic systems.

B.Tech in Computer Science & Engineering (AI & ML)
Brainware University

My projects range from agent harnesses and orchestration to RAG pipelines and LLM-powered backend systems. I've published REXA and somoy on npm, and built and deployed applications including DocSense and Resumark.

I'm looking for an internship where I can contribute to backend and AI systems, work with an engineering team, and deepen the experience I've gained through these projects.
